A streak-free mirror is not about the cleaner — it is about the cloth and the motion. Paper towels leave lint, circular rubbing moves the dirt around, and cleaner left to dry leaves its own film. The right way takes two minutes: a microfiber cloth, a zigzag wipe, and a dry buff.
Mirrors streak for three reasons: the cloth leaves lint, the rubbing moves dirt instead of removing it, or the cleaner dries on the glass before you wipe it off. Paper towels are the worst offender — they shed fibers that catch the light. Circular rubbing is the second: it spreads the film in circles instead of lifting it off. And too much cleaner is the third: a puddle of cleaner dries into its own streaks.
Dust it first. Wipe the mirror with a dry microfiber cloth first: dust, hairspray, and toothpaste specks come off dry. Cleaning a dusty mirror wet just turns the dust into mud.
Spray the cloth, not the mirror. Spray the cleaner on the cloth, not on the mirror. Spraying the mirror runs cleaner down into the frame, where it sits and eats the backing. Two or three sprays on the cloth is enough.
Wipe in a zigzag. Wipe in a zigzag, top to bottom, with overlapping passes. The zigzag lifts the film off instead of pushing it around in circles. Work the whole mirror before the cleaner dries — speed matters more than pressure.
Buff with a dry microfiber. Buff with a second, dry microfiber cloth, same zigzag. The dry buff takes off the last film the wet wipe left behind. If you see streaks, buff again — the mirror is not clean until the dry cloth comes away clean.
Fix the edges and the corners. Clean the edges and the corners with the corner of the cloth or an old toothbrush. Cleaner and grime collect at the frame edge, and the edge is where the streaks hide. Check the frame: cleaner sitting in the frame eats the mirror backing over time.
Clean it last. Clean the mirror last, after the shower and the sink. Steam and splashes undo a clean mirror in minutes — do the mirror after everything else is done. A clean shower head helps the whole bathroom — the shower head cleaning guide covers getting the spray back.
A 50/50 mix of white vinegar and water works as well as store-bought glass cleaner, and a single drop of dish soap cuts the greasy film from hairspray and toothpaste. Never use vinegar on a stone frame — it etches the stone. Hard water leaves its own marks on glass — the hard water stain guide covers removing them without ruining the surface.
A thin layer of shaving cream, buffed off, keeps the mirror from fogging for a few days — or use an anti-fog spray made for mirrors. The real fix is ventilation: run the exhaust fan during the shower and for 30 minutes after, and the mirror never fogs at all. A loud fan is a fan that needs cleaning — the bathroom exhaust fan cleaning guide covers why yours is so loud.
Glass cleaner or a 50/50 vinegar-water mix, wiped with a microfiber cloth in a zigzag and buffed dry with a second microfiber. No paper towels — they leave lint.
Usually the cloth or the motion: paper towels leave lint, circular rubbing moves the film around, and cleaner left to dry leaves its own streaks. Wipe in a zigzag and buff dry.
Yes, on the glass — a 50/50 vinegar-water mix works well. Never use vinegar on a stone frame: it etches the stone.
